2.Ulnar neuropathy.
Journal of the Korean Medical Association 2017;60(12):951-957
Cubital tunnel syndrome is the second most common compressive neuropathy. Its diagnosis is largely based on clinical findings. It has been well known that patients with mild to moderate grade of cubital tunnel syndrome have a high chance of spontaneous resolution, while those with severe degree do not. Thus, the former is treated with conservative methods initially, and the latter is indicated for surgical intervention. There are three types of surgical techniques for cubital tunnel syndrome. Of these, in-situ decompression technique has been gaining popularity as it is simpler and shows similar efficacy with less complications compared to other techniques. In this review, we deal with current concepts of the cubital tunnel syndrome pertaining to the primary clinical practice.

PURPOSE: The purpose of this prospective study is to examine the anatomical variations of the branches of the medial antebrachial cutaneous nerve in Koreans encountered during cubital tunnel surgery. METHODS: Ninety two patients with cubital tunnel syndrome were treated with a standard approach from December 2008 to July 2012. The position of the branches of medial antebrachial cutaneous nerve was evaluated based on the medial humeral epicondyle with the elbows fully extended. RESULTS: At least one medial antebrachial cutaneous nerve branch was found during the surgeries in all patients. The average number of crossing medial antebrachial cutaneous nerve branches per patient was 1.6. Thirty-eight percent of the cases showed that the medial cutaneous nerve branches cross proximal to the medial humeral epicondyle within 1 cm. Eighty-two percent showed that the medial antebrachial cutaneous nerve branches cross distal to the medial humeral epicondyle within 1.9 cm. CONCLUSION: When using standard approach during cubital tunnel surgery, more than one medial forearm cutaneous nerve is found. Therefore, understanding the general position of medial antebrachial cutaneous nerve branches helps avoid iatrogenic damage to this nerve during cubital tunnel surgery.

Postoperative heterotopic ossification of the elbow after surgery for treatment of acute trauma such as fractures and ligament/tendon ruptures has been well-documented. However, literature concerning heterotopic ossification after medial epicondylectomy is scarce. We report on two cases of heterotopic ossification that occurred following medial epicondylectomy for medial epicondylitis and for cubital tunnel syndrome. Preoperatively, calcifications around the medial epicondyle were observed in both patients. These cases suggest that medial epicondylectomy, in the presence of pre-existing calcifications, may pose an increased risk of postoperative heterotopic ossification of the elbow.

PURPOSE: To evaluate the surgical outcomes and the clinical factors affecting the results of subcutaneous anterior transposition of the ulnar nerve in cubital tunnel syndrome. MATERIALS AND METHODS: Eighteen patients diagnosed as having cubital tunnel syndrome and treated by subcutaneous anterior transposition of ulnar nerve were investigated retrospectively. According to preoperative Dellon's staging, 2 patients (11%) were in mild stage, 5 (28%) in moderate and 11 (61%) in severe. Results were evaluated using Dellon's staging and Mowlavi's classification. RESULTS: According to Mowlavi's outcome status, 2 patients (11%) showed total relief, 10 (56%) improvement, 5 (28%) no change and 1 (6%) was worse, therefore the results were satisfactory in 12 patients (67%). Patients with less severe symptoms received surgery within a year of symptom onset and showed better results. CONCLUSION: The result of subcutaneous anterior transposition of ulnar nerve in cubital tunnel syndrome is comparable to that of other surgical methods, but it is easier technically. Better results may be anticipated when surgery is performed within a year of symptom onset.

6.Operative Treatment of Cubital Tunnel Syndrome: A Comparison of Medial Epicondylectomy and Anterior Transposition of the Ulnar Nerves.
The Journal of the Korean Orthopaedic Association 2002;37(6):704-708
PURPOSE: The aim of this study was to compare the results of medial epicondylectomy and anterior submuscular transposition of the ulnar nerve in patients with primary cubital tunnel syndrome. MATERIALS AND METHODS: Thirty patients with primary cubital tunnel syndrome formed the basis of this study. Eighteen patients underwent medial epicondylectomy and twelve patients underwent anterior submuscular transposition of the ulnar nerve. The mean follow-up period was 35 months. Postoperative clinical results were assessed using Gabel and Amadio's rating scale which evaluats pain, sensory and motor function in four grades. Clinical results were compared between two groups in McGowan grades two and three. RESULTS: Two excellent, twelve good and six fair results were obtained in patients with McGowan grade II. In McGowan grade III, three were good, six fair and one was poor. No significant difference in the results was observed between two surgical groups. CONCLUSION: Medial epicondylectomy and anterior submuscular transposition of the ulnar nerve showed no difference in results between patients with primary cubital tunnel syndrome. It seems that medial epicondylectomy is more appropriate because of its simplicity during operation and in terms of postoperative management.

BACKGROUND: The aim of this study was to assess the consistency between preoperative ultrasonographic and intraoperative measurements of the ulnar nerve in patients with cubital tunnel syndrome. METHODS: Twenty-six cases who underwent anterior transposition of the ulnar nerve for cubital tunnel syndrome were enrolled prospectively. On preoperative ultrasonography, largest cross-sectional diameters of the ulnar nerve were measured at the level of medial epicondyle (ME) and 3 cm proximal (PME) and distal (DME) to the ME on the transverse scan by a single experienced radiologist. Intraoperative direct measurements of the largest diameter at the same locations were performed by a single surgeon without knowledge of the preoperative values. The consistency between ultrasonographic and intraoperative values including the largest diameter and swelling ratio were assessed. RESULTS: Significant differences between ultrasonographic and intraoperative values of the largest diameter were found at all levels. The mean difference was 1.29 mm for PME, 1.38 mm for ME, and 1.12 mm for DME. The mean ME-PME swelling ratio for ultrasonographic and intraoperative measurements was 1.50 and 1.39, respectively, showing significant difference. The mean ME-DME swelling ratio for ultrasonographic and intraoperative measurements was 1.53 and 1.43, respectively, showing no significant difference. CONCLUSIONS: Ultrasonographically measured largest diameters of the ulnar nerve at any levels were smaller than the real values determined intraoperatively. The ME-DME swelling ratio of the ulnar nerve measured by ultrasonography was consistent with the intraoperative measurement.

OBJECTIVE: The purpose of this study is to evaluate the arteiovenous fistula effects on peripheral nerve in patients with chronic renal failure by nerve conduction studies. METHOD: Nerve conduction studies were performed in 23 patients with chronic renal failure. We not only measured distal latencies, amplitudes, and conduction velocities of median and ulnar motor nerves but also measured same parameters of radial sensory nerves at both upper limbs. In case of pateints with suspected peripheral polyneuropathy, we checked peripheral nerves at one lower limb. The results of nerve conduction studies and the frequency of cubital tunnel syndrome or carpal tunnel syndrome were compared between arteiovenous fistula side and non-arteiovenous fistula side. RESULTS: The amplitudes of median motor, ulnar motor nerves and radial sensory nerve in arteiovenous fisula side are statistically lower than those in non-arteiovenous fisula side (p<0.05). In the 14 patients with peripheral polyneu ropathy, the difference is also statistically significant between two sides (p<0.05). Compared arteiovenous fisula side with non-arteiovenous fisula side, the frequency of cubital tunnel syndrome or carpal tunnel syndrome was not different between two sides. CONCLUSION: Arteiovenous fisula may damage to the peripheral nerve in patients with chronic renal failure.

A 62-year-old female patient suffered from numbness and resting pain in the right ring and little fingers for 3 years. We confirmed cubital tunnel syndrome with electrodiagnostic study and performed the operation. We found seven firm consistent nodules, compressing the overlying the ulnar nerve, proximal to the medial epicondyle in the operation field. Histological finding showed synovial chondromatosis. We report a rare case of a patient with cubital tunnel syndrome caused by synovial chondromatosis.

We evaluated the postoperative results of cubital tunnel release with modified Eaton's method of anterior transposition of ulnar nerve using fasciodermal sling. This study included 12 patients. According to Dellon's classification, patients were categorized 3 groups as mild(n=2), moderate(n=6), and severe(n=4). Through the longitudinal incision on the medial aspect of the elbow, ulnar nerve was released both proximally and distally. And then, ulnar nerve was wrapped with fasciodermal sling about 3 4 cm in size, which was elevated from the fascia of the common origin of the flexor and pronator muscles. Postoperative results were assessed by modified Kleinman and Bishop's rating system. There were excellent in 4 patients(33%), good in 7 patients(58%) and fair in 1 patient(9%). No patient complained of tingling sensation of the ring and/or small finger. Although all patients showed some improvement of key- pinch, grip-power and static 2-point discrimination, those were not statistically significant. Finally, this procedure has advantages as simple operative technique, short postoperative immobilization, and brief rehabilitation period.
